It sped up the <code>pkg install<\/code> command and added more output with <code>-verbose<\/code>. It added visibility attribute to function declarations, and, re-implemented <code>weboptions<\/code> and related functions <code>webread<\/code>, <code>webwrite<\/code>.<\/p>\n<p>It also removed extra semicolons after function definitions, fixed N-D array assignment to prevent out-of-bounds indexing, and, added ability for class constructors (<code>classdef<\/code>) to return a classdef array of itself.<\/p>\n<p>This version also updated the GUI. It fixed the double spaces in translations, improved German translation. It now uses mouse cursor shape from Qt if possible or SVG. And, for Windows &#8220;system&#8221; calls no longer hide windows.<\/p>\n<p>Besides the GUI and core improvements, Octave 11.2.0 also fixed some issues for building system, and, updated the documentation for <code>arguments<\/code> keyword (and add to manual).<\/p>\n<p>Other changes include:<\/p>\n<ul>\n<li>Deprecate <code>all<\/code> and <code>any<\/code> for non-numeric\/non-logical types.<\/li>\n<li>Fix input validation of <code>permB<\/code> input to <code>eigs()<\/code>.<\/li>\n<li>Fix pager in CLI on Windows and disable it in the GUI.<\/li>\n<li>Check floating point subscripts before converting to <code>octave_idx_type<\/code>.<\/li>\n<li>Reject non-finite, non-integer, and out-of-range floating-point index values before casting them to <code>octave_idx_type<\/code>.<\/li>\n<li>Fix <code>norm (S, 2)<\/code> for all-zero sparse matrices.<\/li>\n<li>Avoid potential integer overflow for <code>max<\/code>.<\/li>\n<\/ul>\n<p>For more about the new release, see the NEWS file in the source tarball (see the link below).<\/p>\n<h3>Get GNU Octave 11.2.0<\/h3>\n<p>The source tarball is available to download at GNU website via the link below:<\/p>\n<div class=\"wp-block-buttons aligncenter\">\n<div class=\"wp-block-button is-style-fill\"><a class=\"wp-block-button__link has-vivid-cyan-blue-to-vivid-purple-gradient-background has-text-color has-background\" href=\"https:\/\/ftp.gnu.org\/gnu\/octave\/\" target=\"_blank\" rel=\"noreferrer noopener\">Download GNU Octave (source)<\/a><\/div>\n<\/div>\n<p>Besides building from the source, Arch Linux has already include the new 11.2.0 release in the official Extra repository.
